MACHINE FOR INSERTING FASTENINGS.

To all whom t may concern:

Be it known that I, GEORGE GoDDU, a citizen of the United States, residing at Winchester, in the county of ,Middlesex and State of Massachusetts, have invented certainImprovements in Machines for Inserting Fastenings, of which the following description, in connection with the accompanying drawings, is a specification, like'reference characters on the drawings indicating like parts in the several figures. Y I

This invention relates to machines for inserting fastenings. By way'of illustration the invention is herein shown as embodied in a machine of the type disclosed in United States Letters Patent No. 490,621, granted January 24, 1893, on an application of Louis Goddu, for inserting screw threaded fastenings in the soles ofboots and shoes.

In machines of the type disclosed in said Letters Patent the wire carrying spindle and the shaft from which the several mechanisms of the machine are driven are maintained continuously and uninterruptedly inoperation and manually controlled. means are provided for suspending the operation of the wire feeding mechanism by holding it out of operative relation to its actuator when it is not desired to insert fastenings. In the operation of machines of this type as heretofore constructed, however, difficulty has been experienced by reason of the fact that there was no certainty as to the time in the cycle of operations of the machine when the wire feeding would be resumed with the result that frequently, upon manipulation of the manually controlled means to establish Voperative relation between the wire feeding mechanism and its actuator, for example, to initiate the insertion of fastenings upon a given piece of work, either a fastening shorter than the proper length for the lgiven thickness of work would be inserted or occasionally the machine would fail entirely to insert a fastening in the first fastening location. Various attempts have heretofore been made to provide satisfactory wire feeding suspension mechanisms for machines of the illustrated type but so far as known none 0f these mechanisms has gone into general use.

@ne of the objects of the present invention is to provide a simple and efficient mecha- Specification of Letters Patent.

nism for controlling the establishment of operative relation between the wire feeding mechanism and its actuator to the end that invariably the first fastening inserted after Van initiation of wire feeding movement will be of the full length required by the thickness of the Work, which mechanism will be reliable, economical to manufacture and capable of embodiment readily in machines of said type at comparatively low cost. In accordance with this object the preferred embodiment of the invention comprises mechanism constructed 'and arranged to insure that the initiation of the operation of the wire feeding mechanism will occur only when the wire feeding mechanism and its driving means are relatively positioned so that the first wire feeding movement imparted to the wire feeding mechanism thereafter will be a complete feeding movement regardless of when the means for controlling the suspension of the wire feeding mechanism is manipulated to effect such suspension.

Another disadvantage in machines of the type above mentioned n as heretofore ,constructed consists in the fact that such machines have had no provision for discontinuing the operation of the work feeding means when the wire feeding'mechanism is inoperative. This has resulted in unnecessary wear and tear ofthe work feeding mechanism and furthermore it has imposed upon the operator the necessity of taking care to prevent feeding movement of the work whenever it was not desired to insert fastrenings.

Another object of the invention is to provide work feeding mechanism suspending means which will be adapted to be embodied readily in a machine of the type disclosed in said Letters Patentand which will suspend the operation of the work feeding mechanism whenever the wire feeding mechanism is inoperative.

A still further disadvantage encountered in the useof machines of the said type has resulted from the liability of the work supporting horn to drop from work clamping positionbefore the last fastening desired has been completely inserted. In machinesV of this type heretofore movement of the horn `out of work clamping position has been dependent entirely upon release of Athe horn raising treadle,4 the construction being such that whenever the horn raising` treadle was released the horn immediately dropped from Work clamping position. In consequence the operator could not determine with any certainty the proper time in the `cycle o f loperations of the machine to release the horn especially by reason of the comparatively high speed at whichfsuch machines are run.

An important obj ect Aof .the -.inventio,n to insure that the last fastening desired 1n a before the vhorn is ,permitted .to 1move. out iof work 4clampingfpositicn, .and lt0 this end the illustrated `machine :is provided with means constructed and `arranged to maintain the horn locked in worlrclampingposition until such predetermined :time in .the cycle lof operations as will insurethe complete :insertionpfthe last fastening rega-rdless ofwhen ing mechanism and establishing operative relatiOIl between the wire y,feeding mechanism and its actuator, as well -as ,the means for suspending rthe operation of ,the work feeding mechanism, may be controlled lby `the horn l.raising treadle .so lthat merely by depressing a single treadlethe operator inlay initiate `the loperation of the wire feeding and work ,feeding mechanisms and raise ltlie horn to 4work clamping position, w-hile upon release 0f that treadle the i operation of these mechanisms is suspended 1and the ,horn is moved from work clamping position `in proper time relation.

Although the invention is herein disclosed -with especial reference .to embodiment ina vmachine ofthe ygeneral 'type shown and ldescribed in the above-mentioned Letters ,Patent and various objects and features ofthe intention `have `been .discussed lwith .particular reference to ymachines of `this type, it is to be understood that the ,invention -is `:not intended to be limited thereby since it is contion with the accompanying drawings and the .various novel features of the invention are set .forth inthe appended claims.

fllhemachine lin which Ia preferred jform of the invention is'shown aslembodied is substantially the same as ithat disclosed in said above mentioned iLetters Patent except as vherein fully .described in detail and reference -may be `had `to said :Letters Patent for a more ide-tailed ,description `of parts herein illustratedbutnot fully described.

The-,maehinehas a base 2 which supports ahead 4iliavinggmountedtherein a vertically .disposedspmdle 6 which carries at its upper Eoperating `treadle 18. The `spindle is provided with Ja worm which engages worm `gears L20 upon the forward ends of llateral shafts 22 one ofv which carries the various cams for effecting 4the wire feeding, wire severing, work Yfeeding and horn depressing operations. Preferably these cams are formed to ,cause'two operations of their respective mechanisms .during one complete rotation ofthe cam shaft 22.

The avire iis fed downwardly through the `spindle 6 by a wire feeding and inserting sleeve24 surroundingfthe spindle 6 and slidably mounted on guideways on the machine frame, :the lower end :of said sleeve being provided ywith .wire gripping members 26 Awhich,operate to seize the wire as said sleeve Yis moveddownwardly. Tfhe sleeve 2 4 is re `ciprocat-ed :in the frame to feed a length of wire vand insert -it into the work by a wire Afeed lever 28 pivoted at 30 in `the `machine frame and having ,two forwardly projecting iarms .each carrying segmental `gears 32 `v vhich engage `*respective racks `Bet formed on a yoke attached to the upper end of the Sleeve .211. An upwardly extending arm 36 of the lever-28 carries a cam roll 3.8 which llO isengaged by a wire feeding edge cam on one of the Vcontinuously rotating lateral shafts 22. The Ywire feed lever 28 isnormally held in position to be actuated by the cam 40 to move the feeding sleeve downwardly by a comparatively strong spring 42 (Fig. l) and a rod 44 the Vlower end of which bears on a lug pro-vided on a rearwardly extending arm 46 of the lever 28. After the proper length of Wire is inserted in the work the wire is severed bylwire severing knives mounted in the lower ends of two knife carrying arms which have a common fulcruin on a shaft 47 mounted in the machine frame. I

In order that the wire inserted in the workmay correspond with the thickness of the work clamped between the horn 48 and the fastening inserting mechanism, the eX- tent of feedingmovement imparted to the wire feed lever 28 by the wire feeding cam 40 is automatically varied; This is accomplished by providing on the horn 48 a laterally extending arm 50 to the outer end of which is attached a measuring rod or leg 52 projecting upwardly through a guide 54 on the frame. This rod serves as avariable stop to determine the amount ofmovement in one direction of a coperating rod 56 the lower end of which is also located in the guide 54 and having its upper end pivotally secured at 58 to theend of the rearwardly extending arm 46 of the wire feedlever 28. It will thus be seen that as the horn 48 is moved into position to clamp the work the measuring rod 52 is correspondingly moved in the guide 54 relatively tothe coperatin'g rod 56 and the wire'feed lever 28 canassume a position, relatively to its actuating cam 40 determined by the position of the measuring rod 52 in accordance with the thickness of the work.

When the machine is being used to insert fastenings the spindle 6 and the two lateral shafts 22, one of which carries the various Cams, are continuously rotated and the insertion of fastenings isinterrupted by suspending the'wire feeding mechanism.

- When the wire feeding mechanism is 4operated to cause the insertion of fastenings to beresumed. it is of considerable importance that the wire feeding lever 28 be in such operative relation toits continuously rotating actuator as to provide an initial fasten- Y' ing of thelength required by the thickness of the work clamped by the horn. In accordance withthe present invention, means are provided for automatically suspending the operation of the wire feeding mechanism upon the release of the treadle by the operator and for automatically releasing the wire feeding suspending means at predetermined times in the cycle of operations of the ma- Chine. Theillustrated means for suspending the operation `of the `.feeding mechanism comprises a block 60 slidably mounted in the frame andhaving a slot 62 through which arojects the lower end of the measuring rod 56 to which a sleevestop 63 is adjustably secured by the set nut 64, the stop being of such diameter as to allow it to pass through the slot 62. The block 60 is normally maintained in position for the stop 63 to become seated on a shelf 66 provided at the rear end of the slot, immediately after the wire feed lever has reached its limit of feeding movement by a spring pressed plunger 68 located lin the frame and having its `end bearing upon a lug 70 projecting from the sideV of the block 60. In order to release the wire feeding suspending means automatically at predetermined times in the cycle of rotation of the cam 40 or at times when the amount of wire fed will correspond to the thickness of the work being operated upon the block 60 is automatically removed from under the stop 63 to permit it to pass through the slot 62 into a position determined by the position of the measuring leg 52, as shown in Fig. 5 by an arm 72. The rear end of the arm 72 is pivoted to a stud 74 on one arm 76 of a bell crank lever 104 and at its other end is provided with a slot 75 through which projects a vertically disposed rod 78 bolted to a yoke member 80 which is mounted for vertical movement in guideway 82 in the frame. The slot 7 5 allows for the play of the arm when it is in inoperative position. A spring 84 surrounding the rod 78 holds the forward end of the lever 72 near the upper end of the rod. The yoke member is secured to the upper end of a rod 86 the lower end of which is connected to one arm 87 of a treadle lever 88 fulcrumed on the shaft 90. A strong compression spring 92 surrounding the rod 86 and interposed between a guideway 94 on the frame and a stop 96 on the rod acts normally to keep the forward end of the treadle raised. The arm 72 is provided with a projectin catch 98 adapted to engage the projecting ug 70 on the block and to move the block inwardly against the tension of the spring pressed plunger 68 after the arm has been moved into operative position by the treadle. The movement of the arm 72 is effected through connections with the mechanism for actuating the wire severing arms 45 to sever the length of wire inserted in the work. The wire severing cam 114 is provided with toes 112 which are adapted to engage a hardened steel plate 110 attached to one endA of a lever 106 fulcrumed on the stud 108 and connected at its opposite end through the link 100 to one arm of the bell crank lever 104 fast on the shaft 47. The forward end of the shaft 47 is provided with gears, not shown, which mesh with coperating gears on the wire severing arms 45 to cause an appreach of the arms to sever the wire, when the shaft 47 is partially. rotated as fully described in said above mentioned patent. It -will thus be seen that as the bell crank 104 is oscillated to cause the operation of the wire severing arms 45 the arm 72 which is attached to the arm 76 of the bell crank may also be moved rearwardly to remove the block 60 from under the stop 63 on the coperating measuring leg 56. A depending arm 115 on the lever 106 engagesa cushioning pad 116 located in a recess in the frame of the machine to reduce the shock and vibration incident to the return of theI lever 106i into position to be engaged -by thetoes 112. In order tomaintain the block 60 in inoperative or suspended position after having been, initially moved into suchdposition by the arm 72 the yoke 8() isrprovi ed with a latch 118 pivotcd on a stud 120 and supported at its forward end in substantially horizontal position by a plugV 122 seated on a spring 124 located in a recess in the yoke. The` forward end of the ,latch 118 is adapted to engage a lip 1126 projecting from the bottom face of the block 60 and hold the block, against the tension of the spring pressed plunger 68 during the time the yoke is nits operative position and the fastenings are being inserted.

In machines of this typeheretofore constriilcted the work is fed after each insertion; of a fastening by a feed wheel which is intermittently rotated by a continuously rotating actuator. When the work feeding mechanism is thus: kept in motion after the fasteninginserting operation` has been 'stopped the parts are subjected to excessive wear. Also: when the work is presented to the machine to` receive fastenings the feed Wheel is not in timed relation to the insertion of the initial fastening; therefore the work often becomes displaced. The work feedingmechanism herein disclosed is. auto mati'oally suspended simultaneously with the stopping of the insertion of fastenings and is automatically rendered operative upon the. initial movement of the wirefeed mechanism to insert a fastening The illustrated preferred embodiment of work feed ing mechanism comprises a feed wheel 128 having a beveled gear on its under side which meshes with a gear on: the outer end of the shaft 130, the opposite end of the shaft, being provided with a pinion 132. This pinion is loosely mounted on the shaft 130 and. is engaged by a rack on one arm 134 of a. two armed lever fulcrumed on the shaft 136, the other arm 138 of saidl lever being arranged to be engaged by a cam roll 140 on the lower end of a lever 142 fulcl'umed on a stud 144` in the machiner frame. The upper end of this leverl is provided with a cani 17011145, which is adapted to travel in a cam track the wire feed cam 40; Ai spring pressed' plunger located` in. a recess in a lug 148 on the side of the arm 134 and bearing against the frame tends to cause the lever to follow the movement of the lower end `of the leveri142 and return the work feeding lever to its normal inoperative position or to the left in Fig.` 3.' A pawl 150 carried by the pinion 1321 is adapted to engage a coperating Vratchet wheel 151 fast on the shaft 130 to effect rotation of the feed wheel in work feeding direction when the arm 134; is moved in operative direction. W'hen the arm 134` is returned? to itsA inoperative position under` the influence of the spring plunger in the lug` 148 the pawl rides over the teeth on the ratchet wheel 151. The feed wheel* isV automatically locked in its inoperative position by a latch 152 pivoted on a studi 154 and adapted to position itself under a projection 156 on the hubA of the two armed: lever. Thelatch`152` is provided with a tail piece 158 which is engaged by a spring pressed plunger 160aeting normally to position the latch under the pro# jection 156 In order that the work feed'- ing mechanism may .be automatically released from itsrlocking means or from the latch. 152 in` timed relation tothe insertion of the initial) fastening in the work the measuring rod 56` is provided with an oil-'set arm' 162 carrying at its lower end an adjustable stop 1:64 arranged to contact with thetaill 158 ofthe latch and move it out of the way ofthe-projection 156 during downward movement of the rod 56 preliminary to the insertion` of the initial fastening. The-latchk 1'52is` retained in unlocking position during the fastening inserting operationbyV a latch 1166 pivot'ed` on the yoke 80 in position to hookover the tail piece 1585 ofthe latchf152.

As above suggestedgan important fea-ture of the invention `is the provision of an improved organization of` mechanism whereby a single treadle may be utilized to render the machine operative to insert fastenings and to effect a movement oi' the lhorn into work clamping position and maintain said horn ini such` position until after the final fasteninghasbeen completely inserted the work. In the illustrated embodiment of this feature of the invention, horn 48? is carried upon the upper end of' a horn supporting shaft 168latta'ched at 169`to the forward end of a lever 170. fulcrumed` on a stud 172 in the base ofthe machine. The other end of this lever is connected through toggle links 174 and 176 and-a 'connecting link 178 to the curved outer endY 180 of the main treadle lever 88. One end ofthe toggle link 174 is pivotally secured at 179 to the hooked end 1S2Lof-'a lever-1184 also fulcrumed on the stud 1172 andl provided with a member 186having a bore in which is` received the lower end of a rod 188 4forming part of' the automatic horn release and work thicknessgcompensating mechanism 190. The work thickness compensating mechanism herein shown is of well known construction and is fully shown and described in United States Letters Patent No. 388,455, granted May 29, 1888, on application of L. Goddu. A spring 192 surrounds the rod 188 and is confined between the machine frame and the collar 194 'on said rod, the spring acting normally to maintain the hooked end 182 of the lever in its lowermost position, The horn is periodically de'A pressed to permit the work to be fed after each insertion of fastenings through the horn depressing and work thickness compensating mechanism which is actuated by a cam (not shown) on the main shaft of the machine to raise the curved end 182 of the lever 184 about its fulcrum 17 2l which in turn lifts the straightened toggle-174 and 176 and oscil lates the lever 170 about its fulcrum to permit the horn to drop the desired distance.- The `horn is prevented from immediately moving into work receiving position when the treadle is released by the operator until after the complete insertion of the fastening then being inserted. This is effected by means which are rendered operative through the release of the horn to allow the work to be fed after the final fastening has been completely inserted. rl`he illustrated'means comprises alatcu 196 pivoted on the stud 172 and having its forward end arranged to fall into engage-ment with a shoulder on a block 198 secure-d to the side of the connecting link 178 as the link is moved upon depression of the treadle to straighten the toggle 174 and 176as illustrated in Fig. 7.

The forward end of this latch moves with the block 198 and maintains the toggle straightened at all times during the normal operation of the machine, that is, While the treadle 88 is depressed. When the operator removes his foot from the treadle to stop the insertion of fastenings a finger 204 pivoted at 206 on theframe is allowed to swing into engagement with teeth 202 provided on the rear face of a tail piece 200 of the latch thus locking the latch against oscillation about its pivot. The treadle is thus pre vented from assuming its inoperative position owing to the toggle being held in straightened position by the latch, and therefore, the horn remains in work clamping position.

llhen the lever 184 is oscillated by the horn release -to depress the horn sufliciently to permit the work to `be fed after the final fastening has been inserted in the work, the raising of the toggle 174, 176 allows the block 198 to free itself from the latch 196 which is` locked by the finger 204 whereby the togA gle instantly becomes broken and thehorn assumes its work receiving position.

The operation of the machine hereinabove"- described is asfollows: The spindle `6gand the main shafts 22 of the machine are set in continuous rotation by the depression of the treadle 18. Upon depression of the foot treadle 88 the toggle 174, 176 is caused to be straightened and the horn raised into work clamping position. Movement of the treadle 88 also raises the yoke 80 through the rod 86 and positions the arm 72 into operative relation to the block 60 which in its inoperative position, as shown. in Fig. 4, is located under the stop 68 on the rod 56 thus holding the feed lever 28 out of engagement with the wire feed cam 40. The adjustable stop 208 on the treadle lever 88 has also engaged the tail 207 ofthe linger 204 and allowed the latch 196 to fall into engagement with the block 198 on the link so that the toggle is locked in straightened position. As one of the toes 112 on the cam 114 engages the plate 110 on the end of the lever 106 after the arm 72 has been raised into operative position by the treadle it moves the lever 72 through the connections 100, 104 and 76 in a direction to withdraw the block 60 from under the stop 68. The wire feed lever 28 is immediately moved under the influence of the spring 42 and rod 44 in a direction to move the cam roll 88 into position to be en gaged by the second portion of the cam 40 when it comes into position during the next half cycle of rotation of the cam. It will be seen that the wire feeding lever 28 is not in engagement with the wire feeding cam 40 to insert a fastening during the first half rotation of the shaft 22 and the cams carried thereby and that the utilization of the first operation of the wire severing cam, which operation occurs immediately after the first half rotation of the shaft 22 has been completed, to release the block 60 from under the stop 63 enables the wire feed lever to position itself relatively to the cam 40 at such time as will allow the succeeding half of the wire feeding cam to impart its maximum throw to the wire feed lever 28. The amount offeed imparted to the lever 28 however is determined by the thickness of work clamped by the horn which thickness corresponds to the position the measuring leg 52 has assumed in the guide 54. The raising of the yoke 80 throughthe rod 86 upon the depression of the treadle causes the latch 118'to engage the lip 126 ofthe block 60 and thus maintain the block 60 in released position, that is, in position to allow the stop 63 on the measuring leg 64 to pass through `the slot 62 in the block. The downward` movement of therod `56 to position the wire `feed lever relatively to its actuating cam 40 also causes the adjustable stop 164 to contact-with the tail 158 of the latch `152 of the work` feed arm. The latch 152 is held Clear `of the projection 156 by the latch 166 pivoted on the yoke 80 and brought into position to engage the tail 158 of the latch when the yoke is raised by the initial depression of the treadle. After each fastening has been inserted the horn is depressed a sufficient distance to permit the work to be fed through connections 190 and 188 between a cam not shown and the rear end of the lever 184. This connection with the rear end of the lever 184 turns the .lever about its fulcrum 172 and causes its forward end` 182` to raise the rear end of the lever 170 through the straightened toggle member 174, 176 which inturn lowers the forward end of the lever 170 to which the horn is attached. The latch 196 at this time moves with the toggle 174, 17 6 and prevents it from being broken.

fastening by the feed wheel 128 which is rotatedby connections 180, 134 and 138 and lever 142` tothe cam 40. The work feed lever is then returned to its normally inoperative position under the influence of the spring pressed plunger in the lug 148, the

`pawl 150, riding overthe teeth on the ratchet 151 soas to prevent the rotation of the shaft 130 during the return of the parts. When the operator removes his foot from the Vtreadle 88 to stop the insertionof fastenings the lost motion in the treadle mechanism allows the .treadle to rise sufliciently to remove the stop 208 from engagement with the tail 207 of the Enger 204 whereby the finger immediately drops into engagement with the teeth 202 provided on the latch member. The latch, being locked, is prevented from following, the next movement of the toggle members as they are raised by the horn release after the final fastening has been iiiserted'.v The-block 198 being free of the latch 196 allows the toggle to be broken, whereby the horn is loweredinto work receiving position andthe treadle88 raised intosnormal position. Since the-.hornf release mechanism positively controlledin` timed: relation to the fastening insertingwords, since themechanism, or in other A horn release is never operated until after the final fastening has been inserted, it will be noted that by causing` the treadle mechauntil such ienismY to be positively locked the complete insertion lease occurs insures of [the final fastening at which `the operator stop the machine. complete release `of releases the treadle to Simultaneously with' the the treadle the bloc-lr 60,

under. the iniiuence of the spring `68 may position yitself under the stop 63 of the measuring'leg tosuspend further operation of the wirev feeding lever, since the wire fecdinglever is at this time at the limit of :its-

feeding movement. 'Also the latch152 immediately snaps thus suspending and the work feeding means.
